Best Hole Saw For Fiberglass Buying Guide

If you intend to spend some bucks on a hole saw, you have to consider different factors like material, size, design, durability, and ease of use. These factors will help you to make a quicker decision. Let’s dig into these factors.

Material

Material is the most important factor as the performance of the hole saw mostly depends on it. If the hole saw is made of strong material, it will handle hard fiberglass without any hassle. So, we suggest you go for materials like carbon steel and tungsten carbide.

Carbon steel is a strong material that lasts longer and cuts the fiberglass quickly. On the other hand, the tungsten carbide-made blades remain sharps for a longer time and offer clean cuts.

Design

The design of the hole saw is important for getting a sharp cut without broken edges. Actually, the hollow design of bits allows the water to flow up inside and keep the drill cool while working. So, the hollow design will keep the sharpness for a long time.

Some hole saws come with an adjustable blade design that covers most of your needs and gives clean cuts at fiberglass. Also, some hole  Blade designs include a shield that maintains clear visibility and catches mess for easy cleanup.

Sizes

Size is another important factor as you need multiple sizes of holes for work. So, keep sure the kit includes multiple bits of different sizes. As common hole size varies up to 5 mm to 40 mm, select a kit that can cover at least these sizes.

Nowadays, there are adjustable fiberglass hole saws that can be adjusted to get multiple sizes of holes. It is a better option as you don’t have to change the bits while working on different hole sizes.

Coatings

The coating helps to resist corrosion and makes the hole saw sharp to ensure a clean cut. So, it is better to select a hole saw with nickel-plated coating or diamond coating.

Nickel-plated coatings resist corrosion and make these bits more efficient. On the other hand, the diamond coating offers sharp and efficient cuts within a few seconds.

Durability

If the hole saw is not durable enough to handle fiberglass, you have to change it frequently. Some hole saws also lose their sharpness after using for a few holes. So, you have to select a hole saw that won’t break easily and remains sharp for a longer time.

Ease of Use

For making holes on fiberglass, you will need a little bit of a strong hole saw for a clean and sharp cut. Also, make sure the hole saw can handle other materials so that you can use it when needed.
